    Hello all,

    We have a lemon tree that has been having its leaves curling for a few years now. The leaves curl, and have a silverish skin on them.

    It usually seems to target the newer leaves, or at least it affects those the most.

    We have tried cutting off the twigs to the infected parts, as well as applying Cooke KOP-R-Spray Concentrate. It doesn't get rid of it, but it does seem to improve the situation.

    We also have tried applying Malathion, to no avail.

    Any and all help will be appreciated.

    It's probably Leaf miners.

    I agree the damage does look like leaf miners are at work on those leaves.

    You need to do 2 things repeatedly. Get pheromone traps for them and spray around the plant every few days for about like 2 months. Be relentless even if you don't see damage anymore.

    @waretop: Do you recommend any particular spray or brand of pheromone traps?

    No. You are in the area that should help you. Go to The Depot or a garden center and they should help you allot.

    Please do come back and let us know what they say and what you den of doing. That's how we all learn around here.
